This invention relates to splitting machines -and is herein illustrated as embodied am-achine of the type disclosed in United States-Letters Patent No. 1,757,160,granted s May 6, 1930-, on an application filed in the nameof myself and Frank B. Keall, said machine being particularly adapted to split the heel end of a sole to form a thin flap which, after the sole has been incorporated to in ashoe, 'may'be bent down and attached to the breast of a Wood vheel.

This? machine comprises a knife, a support for; a'blank, 'apresser' roll located close to theknife an'd adapted to hold the blank firmrs 1y against the; support at that locality, and

means for reciprocating the support so that the-blank is first fed to the knife to cause the flap tobe formed and is then Withdrawn from the knife.

In machines of this general'type it is essential that the sole or other blank be placed accurately in position upon the support in order to ensure that the cut produced by the knife-shall be-of the desired 'directionand' 2 extent. To this end, according to one feature of the invention, there 'is-provided-astop or. gage against which the leading end of the blankmay be placed, and means for moving the'stopout of the path of movement of the 36 blank prior to the movement of the blank to permit the blank to be presented by move ment ofthe Work support to the splitting mechanism. Inthe illustrated machine the stopnormally rests upon the work support just 'i n: front ofthe splitting mechanism and islifted out of the path of the blank before power is applied to the machine to movement tothe worksupport. I -Aiiter the-blank has, been properlyxposition'ed upon the support, it is desirable that it be? prevented from movement With respect to the support during the splitting operation. According,- therefore, to another feature of the invention there is provided holding 55 means in the form ofa roll which is normalhas been positioned upon the support.

impart ous camsof the' machine and is driven ly in inoperativevpositionbut is moved into engagement "With the blank after the blank In the illustrated machine thisxroll is normally spaced above'thesupport, and is moved down w to press the blank against the support after the stop referredto above has been'lifted; and,-in order to facilitate the operation of themachinaboth the stop'zand the roll are connected-With an operator-controlled mem- 55 her, such as a-treadle, in such mannerthat movement of this member first brings the roll down upon the blanln'then' lifts the stop, and finally applies power to the. machine.

'These and other features ofithe invention including certain details of construction and combinations of parts will'be described as embodied in an illustrated machine and pointed out in" the-appended claims.

Referring now to-the accompanying ings,

Figurerl is a detailview of part of the roll of thesplittingmechanism and the mechanism for driving the roll; and v I Figure :5 is -a side elevation of part of a machine having-embodiedxin it a modified construction. a

The illustrative machine comprises a horizontal canrshafthvvhicli carries the varidrawthrough a one-revolution clutch (:not shown),

ahorizontal table 2 to support a loose sole so to the knife to define the thickness of the ilap to be split, and a fiat straight-edged splitting knife 4.

The front portion of the frame of the machine is provided with a horizontal dove tailed guideway in which is mounted a table slide 5 having fixed to itthe horizontal table or support 2, the top of the table being provided with teeth (not shown) which prevent the work from slipping. The table is adapted to be reciprocated horizontally parallel to the plane of the edge of the'splitting knife 4. Motion is given to the table 2 by a pin 6 carried by the table-slide 5 connected a link 7 with the top end of an upright rocking lever 8, which is pivoted to the frame of the machine and to which rocking motion is im parted by a cam (not shown) on the camshaft 1 through a cam-roll 9 carried by a bellcrank lever 10 pivoted at 11 to the machine frame and connected by-a link 12 to the lever 8. The arrangement is such that, on the starting of the machine, the table 2 is moved to carry the sole to the splitting knife, and

thereafter the table is retracted to initial position to carry the split sole back again clear of the machine instrumentalities.

The knife 4 is fixed to' a knife-carrier 13 mounted in a bracket 14, whichis carried by the machine frame and is formed at its front end with a head to carry the presser roll 3 which cooperates with the knife. 7 The front of the bracket 14, as has been mentioned, is extended to form a head; at each side of this head is a guideway'in which is mounted for up-and-down sliding movement a slider 15 which carries at its lower end a bearing. for a trunnion of the roll 3. Each slider 15 has threaded into it a screw 16' which is rotatably mounted in the bracket 14 but prevented from endwise movement therein. Each screw 16 has fixed to its upper end a gear 17:1nesh1ng respectlvely with gears,

one of which is shown at 18, said'gears being '1' fixed on a shaft 19 rotatably mounted in bearings formed on caps 20 which cover the guideways of the sliders 15. The shaft 19 has fixedon it a handwheel 121 by which it may be rotated to adjust the roll 3 vertically towards or from the knife edge. To indicate the distance of the roll 3 above the knife edge and to assist the operator in adjusting the roll a pointer 21 is pivoted to one of the caps 20 and swings over a scale 22 on the cap when the roll 3 is adjusted. The pointer 21 is connected by a link 23 to a lever 24 pivoted to the cap 20, and the lever 24 has fixed in.

it a pin 25 which passes through a substantially vertical slot in the cap 20 andinto a horizontal slot in the slider 15.

In order to accommodate soles of varying thickness the bracket 14, which carries the splitting knife and the roll 3, is not fixed to the frame of the machine but is pivoted at 26 thereto, and its forward end is yieldingly urged downward through a spring 27', the efiective strength of which may be ad usted by adjusting a collar 28 on a rod 29.

pivoted to the machine frame, the other arm of the lever carrying a roll 33 operated by a cam (not shown) on the cam-shaft 1 at the correc time to lift the sole-pressing roll from contact with the work. The forward end of.

the bracket 14 may be adjusted upwardly ordownwardly to adjust the roll 3 and knife 4 relatively to the upper surface of the table 2 by an eccentric sleeve 34 rotatably mounted on the pivot 26 and in the bracket 14. The sleeve 34 has on it an arm 35 which carriesa spring plunger 36 arranged to enter any one of a series of holes 37 formed in a segment 38 fixed on the machine frame. By this means the forward end of the bracket may be quickly adjusted and the eccentric sleeve locked in adjusted position.

The roll 3 is preferably rotated so that it assists the table in feeding the work and for this reason one of the trunnions of the roll has fixed on it a pinion 3 (Fig. 4) which meshes with a rack 40 carried by the table. To maintain the rack and pinion always in mesh when the roll rises, the rack is pivoted at 41 to the table, and its rear end is supported by rolls 42, 42 which are carried by an arm 43 pivoted on the trunnion of'the roll. Such a driven roll is of particular advantage if it is desired to present to themachine a second time a sole which, during the original operation, has not had its flap formed as long as desired. The driven roll then ensures? that the split flap siall be fed to the knife as the table feeds the sole.

In order to hold the work firmly against the work support during the splitting operation, operator-controlled holding means is provided in the form of an auxiliary presser roll 47 which engages the work in advance of the presser roll 3 and knife 4, which constitute the splitting mechanism. East to the frame of the machine is a rigid armor bracket 150 having mounted in it a rock-shaft 143. Fast tothis rock-shaft on one side of the bracket 150 is a bell-crank lever 44 having a forwardly projecting arm and an upwardly projecting arm. t the other side of the bracket 150 there is an arm 45 corresponding to the forwardly-projecting arm of the bellcrank lever 44 also fixed on the shaft 143. The front ends of these arms are pivotally connected to the upper end of a floating casting 46, the lower end of which carries the 1-,see ,245

treelyq'otatable clamping'or auxiliary pressing-roll 47. Theu'pwardl -projecti-n g arrn-ol thebell-crank lever t l i's pulled by' a spring in-ysuch a direction as to rock thebellcra-n-l'r l so as; to raise the casting 4-6 and with it the auxiliary pressing; roll 47, its highest position, which position is deter m-i'ned by a stopscrea' 4:9wit'h which the said th'atthc position of thelower end of the cas ing, and therefore; of-tlie roll 47, may bead just'ed forwardly and rearwardly of the anachine. The upper end of the casting is prouidedwi'tliavertical recess in which there is' i'n'ounted a vertically-movable plunger 51, normally pressed upwardly by a spring (not shown) located in the bottom of the recess.

'Pi'vote d' at 52'to-theri-g-id arm 1500f the machine; is a bell-crank lever 53 one arm 5 of which extends forwardly and engages the top of the plunger Theothera-rm 55 of the bell=cranklever 53 has connected to-it one end 01 a rod 56 the otherend of which is connected to a bell-crank lever 57 pivoted at 58 to the arm'1'50p The bell-cranklever 57 is connected by a: rod 59 to a lever 'GOfiXe'd on a pivot 61 rotatably mounted inthe frame or: the machine, and connected by a rod 62 I to a t'rea-dle (not shown)". Also fixed. onthe pivot61 is an arm 68 having connected toit a clutch actuating rod; 64 The; first part of the downward movement of the treadl'e inovest-he roll 17 into'engagenient with the work on' the table 2' and. further downward imovementof the treadle depresses the plunger 51 in the casting a6 and also, through the rod 64*, actuatesthe clutch to start themachine. 7

In order that. the sole, may be positioned readily in correct position longitudinally 'withrespect tothe splittingknife the follow- 'ingdevice is provided Near the lower-end oitthe floating casting- 16 (Figure 1) there :is carried a sole-stop which is adapted to move upwardly and downwardly, being normally held downwardly in contact-with the table ofth'e machine so that if a sole, in

being positioned in the machine, is moved i rearwardlyonthe table its rear endis stopped as soon as it comes into contact with this pairs of" substantially parallel arms 71, 72

' pivoted to the casting 46, the arm 72 being pivoted: to the upper'en'd of the-stop 7-0 and the arm 71 to the middle-thereof. Oneof the arms'ZQ has projecting firom it an 2mm 7 3whichis connected a 1inkV74s-tlo an arm pivoted to: the stationary arm: The arm 75 is:connected by a link 76totheiar1n- 5.4:

of the lever 53'. When: the lever 5Biis swung forwardly aboutitspivotby itsiconnections presses the plunger 51 and compresses the plunger spring: lD uing this lat ter'movementof the lever 53 the arm 7511s pressed down by the link T6 and through the Link/7.4

raises the twins 72,71 and thereby raises the stop 70; and during-'thislatt'er movementot the'lever 53, as has been explained, tJh-eclutch is tripped testa-rt the machine; The operator holds the tr'eadl'e down duri ng the'splitting operation;

A modified form of mechanism for depressing thecasting 146 (which corresponds to the casting 16) and roll 47 is shown in Figure- 5 and comprises a forked liand lever 65 which is pivoted by its fork at 66 50v a forked bracket 67 that extends rearwardly and upwardly from the topof" the floating casting 146, the front of the'fork of the lever 65 resting upon" the top of a plunger 1 51. The-lever 65 projects forwardly into a position in which it maybe grasped byt erator. The arrangement is such that normally the floating casting 1 1-6" (and therefore the roll 47.) isheld upwardly clear of the workby thespring 48 of the-bell crank lever 1 14'. After the work has been placed in tlie machine, the operator grasps the hand-lever 65 and presses: downwardly, withtlie result that he first depresses the plunger 151 and the floating castingg146 asa wholeagainst the spring 18 of the'bell-crank lever 44: until the {LL depressed further, the pressure on the roll 17 increases as the'plunger-isdepressed downwardly against its, spring intothe recess in the-floating casting; To limit the upward movement of the hand lever 65 and pl unger he op- Y 151 and to. prevent, chattering oft'heghanch lever on the 'plnngenthe hand-lever has a depending lug68 which carries aroll 69 arranged to. underlie and contact" with the forked bracket 67 of the floating casting 146 so that the hand-lever is always-held inconl tact with the top of the spring-pressed plunger.

The floating casting146' near itsiupper end carries a transverse spindle '71 to. whichis fixed a rearward'ly-projecting 7 8: and: a-

forwardly-projecting arm 79, the forward end of the latter being connected by a link through a lost-motion connection to the aforementioned hand-lever 65, and the rear end of the rearwardly-projecting arm 78 being pivoted to the top end of the sole-stop 170; the middle of the sole-stop is pivotally connected by a link 81 with the lower part of the floating casting. The arrangement is such that so long as the hand-lever 65 does not move relatively to the floating casting the sole-stop remains in operative position, but when (after the roll 47 has clamped the work) the plunger 151 yields and the handlever moves down relatively to the casting, then the spindle 77 is rocked and the sole-stop is raised to a position clear of the work. By adjusting the length of the aforementioned floating-casting control link 50, the position of the sole-stop forwardly and rearwardly in the machine may be adjusted with a consequent adjustment of the position of the rear end of the sole in relation to the splitting knife and a correspondingalteration in the length of sole that is split.

The hand-lever may also be used to apply power to the machine if desired. For instance, the aforementioned transverse spindle 77 may be provided with a third arm 82, which may be connected by a link 83 to a rocking lever 84, which in turn may be con nected by another link 85 to the clutch mechanism, the arrangement being such that the clutch is tripped by continued movement of the hand-lever after the sole-stop has been raised from the table.

The operation of this modified form is as follows :The sole is placed on the table 2 and is moved rearwardly until its rear end contacts with and is stopped by the sole-stop 170, which has been adjusted forwardly and rearwardly by adjustment of the length of the floating-casting control link 50. The operator grasps the hand-lever 65 and depresses it; first the floating casting 146 is depressed until the roll 47 contacts with and presses the sole against the table; further depression of the hand-lever causes the sole-stop 170 to rise to clear the sole; still further depression of the hand-lever causes the clutch to be tripped; and the machine starts and operates as already described. The operator holds the hand-lever depressed so as to clamp the sole to the table throughout the operation.
